Watching traditional linear TV has shown a sharp decline among younger adults over the last two to three years and the question is how far it has to go before bottoming out. This report explores the causes and presents our forecasts up to 2020

We see the main causes of this as the growth of online connectivity associated with the proliferation of screens via smartphones and tablets, the increasing functionality of these other screens, the increasing population of connected TV sets and the growing volume of long and short form content that can be accessed over the internet

Examination of current “connectivity” trends suggests that 2013 will prove the peak year of decline. Thereafter we expect trends to stabilise over the next three or four years without fundamental change to the linear TV landscape

Explosive growth in take-up of smartphones and tablets means that the effective size of the internet will increase by several multiples within the next few years. This transformation in scale comes with a major change in character and operating dynamics, creating new opportunities and revenue streams.

Twitter is unique amongst social apps: it gives new users a blank canvas in which they can (and must) create their own social network reflecting their own interests, hence building an ‘Interest Graph’, but onboarding new users remains a challenge.

Revenue at Twitter is now on a $600 million annual run-rate, scaling rapidly since the introduction of ‘native ads’, and seems set for further growth: the key question is whether it can achieve breakout user growth and mass market scale.

The Charter Review of the BBC officially opened with the Culture, Media and Sport Committee’s inquiry into the Future of the BBC asking the question “What should the BBC be for and what should be the purpose of public service broadcasting?” The only obvious answer is that the BBC and public service broadcasting should be for the people of Britain, and the BBC rates highly on different measures of public and audience engagement. The BBC plays an irreplaceable role in the supply of PSB programming that UK audiences appreciate, most importantly news, where the BBC accounts for 70% of TV news time and for 22% of online news time in 2013.

Ofcom has been instructed by the UK government to charge the mobile operators ‘full market value’ for the 2G spectrum they have been using for many years, despite there being no liquid market for the spectrum

Ofcom’s general approach to such an imponderable question is eminently sensible, but we disagree with the detail of their methodology on three key aspects, which makes the current proposed charges over three times too high in our view, effectively charging the industry a one-off tax of £4.5bn

The elevated fee levels are (perhaps) still affordable on their own, but coupled with other recent regulatory decisions the UK is in danger of being seen as a hostile regulatory environment, with negative consequences for future investment levels

The stress on 21st Century Fox’s Italian pay-TV platform is easing as the worst recession of any G8 country is expected to end in 2014, and competitive pressure from Mediaset is weakening

Sky is sticking to a long term strategy, investing in the (unrivalled) quality of its offering and sustaining high recruitment costs. The subscriber base seems to have levelled off, revenues are stable, but profits have collapsed. Management plans cost cuts to raise profitability by 2016

The upcoming auction for the 2015-18 football rights could see Sky gaining more exclusivity at a higher cost, which it would have to recoup mostly by rising prices. The key potential upside resides in an Italian economic upturn – which is only conceivable in a few years

Richard Desmond’s appointment of Barclays to explore the sale of the Channel 5 Group in 2013 has fuelled speculation over prospective purchasers should Northern & Shell be intent on selling this asset

The reported target of at least £700 million, seven times the £103.5 million paid by Northern & Shell to RTL three years ago, reflects a strong performance in 2013, but needs to be against several distinctive factors, including Channel 5’s near total reliance on advertising and the cross-promotional benefits it gains from the Northern & Shell print publications

Regulatory and strategic considerations suggest that neither ITV nor the pay-TV platform operators, Sky and BT, are likely to emerge as serious bidders and that an overseas group from the US is the most likely outcome if a sale is to take place

The BBC Trust has given its provisional approval to the BBC Executive’s proposals for Project Canvas, the JV between the BBC and five partners that aims to enable DTT homes with broadband connections to access IPTV content on their TV sets

Canvas promises to enrich greatly the DTT platform; however, it is likely to encounter fierce opposition during the coming consultation from equipment manufacturers and the pay-TV platform operators, Sky and Virgin Media, especially in relation to its attempts to prescribe the user experience (UX)

We think that the BBC Trust will give its final approval, subject to the conditions specified in its provisional statement, but further delays seem likely and we do not expect Canvas devices to appear in the shops before 2011

In The Netherlands, KPN faces strong competitive pressure on voice and broadband from cable operators historically addressing subscription TV services due to their superior fibre/coax networks – KPN needs to upgrade its ADSL network to increase IPTV coverage and bandwidth to compete effectively on the triple play

KPN is pursuing a multi-technology approach to its network upgrade, deploying VDSL over the existing copper access network as a ‘transitional’ solution, accompanied by deployment of FTTC and FTTH. Currently, 13% of Dutch homes are passed by fibre, with KPN setting a ‘medium term’ coverage target of 30-60% of households

KPN says that FTTC and FTTH trial results show material increases in ARPU and market share, supporting the case for deployment. KPN is assuming entirely the costs of FTTC, but the investment in more expensive FTTH is being made by joint venture KPN-Reggefiber, whose need for finance in mid-2010 will require it to convince debt markets of its business plan for FTTH

This report sets out our thinking on the audience growth potential in the UK during the next decade of video on demand (VOD) programming that viewers can call up via interactive return pathways. VOD may be delivered by cable TV transmission networks directly to the TV set or by wireline broadband IP (Internet Protocol) networks directly to the PC and to the TV in homes equipped with the necessary receiving equipment

The question being asked by many is whether VOD will provide a paradigm shift that sees the decline of linear broadcast channel audiences in favour of non-linear on demand viewing in a TV Anytime future, where people can choose what they want to watch at whatever time they want

After reviewing the evidence from a growing body of research into viewing habits and audience measurement and examining the commercial constraints, we conclude that the traditional linear broadcast model will continue to hold centre stage for many years to come

France Télécom’s Orange TV premium strategy presents an interesting example of diversification into low cost ‘light’ pay-TV offers by an incumbent telecoms operator. Orange Sport and Orange Cinéma Séries are offered exclusively to Orange's 2.55 million TV subscribers, and five quarters after launch, adoption is 20%. This report draws several lessons on this type of venture for other incumbent operators
